  • The age of social AI

    The age of social AI
    2025/10/08
    AI therapists and caregivers. Digital tutors and advisors and friends. Artificial lovers. Griefbots trained to imitate dead loved ones. Welcome, to the bustling world of AI-powered chatbots. This was once the stuff of science fiction, but it's becoming just the stuff of everyday life. What will these systems do to our society, to our relationships, to our social skills and motivations? Are these bots destined to leave us hollowed out, socially stunted, screen-addicted, and wary of good-old-fashioned, in-the-flesh human interaction. Or could they actually be harnessed for good? My guest today is Dr. Henry Shevlin. Henry is a philosopher and AI ethicist at the Leverhulme Center for the Future of Intelligence (CFI) at Cambridge University. In a series of recent papers, Henry has been exploring this brave new world of "social AI" and its philosophical, ethical, and psychological dimensions. Here, Henry and I sketch the current landscape of social AI—from dedicated platforms like Replika and CharacterAI to the more subtly social uses of ChatGPT and Claude. We consider several tragic cases that have recently rocketed these kinds of services into public awareness. We talk about what's changed about AI systems—quite recently—that’s now made them capable of sustained relationships. We linger on the possible risks of social AI and, perhaps less obviously, on the possible benefits. And we consider the prospects for regulation. Along the way, Henry and I also talk about his 81-year-old father, his teenage self, and, of course, the kids these days; we consider whether Social AI, in its potential harms, is more like social media or more like violent video games; we talk about "deskilling" and it's opposite "upskilling"; and we of course take stock of a certain elephant in the room. Alright friends, this is a fun one. We've been wanting to explore this dawning age of social AI for some time. And we finally found, in Henry, the right person to do it with. Enjoy!

  • Brains of a feather

    Brains of a feather
    2025/09/24
    Birds do the darnedest things. They fly, of course. They sing. They hunt in pitch darkness. They hide their food and remember where they put it. They use tools and migrate over astonishingly vast distances—sometimes even sleeping while in flight. How do they do all this? What's going on in their brains that makes these and other remarkable behaviors possible? How did their evolutionary path mold them into the incredible creatures they are today? My guests today are Dr. Andrew Iwaniuk and Dr. Georg Striedter. Andrew is a comparative neuroscientist and Associate Professor at the University of Lethbridge in Canada. Georg is a Professor of Neurobiology and Behavior at the University of California, Irvine. Together they are the authors of the new book, Bird Brains and Behavior: A Synthesis (available open access here). Here, Georg, Andrew, and I consider the deep history of birds—how they skirted the mass extinction event that felled the dinosaurs, and then radiated out into the 11,000 plus species we know today. We talk about how bird brains differ from those of mammals and reptiles—in terms of their size, but also in terms of their major structures, and in terms of their wrinkliness. We tour some of the most peculiar and perplexing bird behaviors, and consider their neural and anatomical underpinnings. Finally, we consider what we can learn from bird brains, not just about birds but about brains in general—how they evolve, how they get wired up, how they do and do not vary. Along the way we touch on barn owls, hummingbirds, megapodes, mallards, pigeons, parrots, starlings, and underestimated waterfowl; we touch on how birds' brains change with the seasons; the enduring mystery of magnetoreception; the possibility of olfactory maps; the optocollic reflex; the social intelligence hypothesis and the extractive foraging hypothesis; precocial versus altricial bird species; split-body gynandromorphy; and the future of non-invasive work in bird neuroscience. Season 7 of Many Minds is now gathering steam. We've got some great episodes in the works for you. Just a little reminder that we'd be grateful—thrilled, even—if you could help us get the word out about our show. You might do this by leaving a rating or a review, or by telling a colleague about us. We really appreciate the support, friends! Without further ado, here's my conversation with Dr. Georg Striedter and Dr. Andrew Iwaniuk. Enjoy!

  • How nature restores the mind

    How nature restores the mind
    2025/09/10
    One afternoon you decide to snub your responsibilities and go for a hike. You spend a few hours in the woods or the mountains. You study the bark of trees, you bathe in birdsong, you let your eyes roam along a distant ridgeline. And you come back feeling better, restored somehow—like you have more energy, more patience, more bandwidth. We've all, I'm guessing, had experiences like this. But what's behind these effects? Why would nature restore us? What's the evidence that it really does? And what is even being restored, actually? My guest today is Dr. Marc Berman. Marc is an Associate Professor in the Department of Psychology at the University of Chicago where he directs the Environmental Neuroscience Lab. Marc is also the author of a new book, Nature and the Mind: The Science of How Nature Improves Cognitive, Physical, and Social Well-Being. Here, Marc and I talk about Attention Restoration Theory—the idea that nature experiences restore our limited capacity for directed attention. We discuss the broader field of "environmental neuroscience," which Marc helped kickstart and continues to lead. We range across studies from Marc's lab that show nature's beneficial effects—on attention, on mood, and on health. We talk about what the active ingredients in nature seem to be. And we discuss the field's prospects for understanding how nature impacts not just the mind, but the brain itself. Along the way, Marc and I touch on: soft versus harsh fascination; the elusive concept of "mental energy"; trees, wood, fire, and rain; the architect and theorist Christopher Alexander; the value of fake plants; fractalness in space and time; curvature and spirituality; and how nature tends to steer our thoughts in certain directions. Needless to say, we're stoked to be kicking off a new season of Many Minds. If you're new to the show, welcome! If you're already a fan, perhaps you'd consider leaving us a rating or a review on your platform of choice. It really does help us reach new listeners.

    From the archive: Revisiting the dawn of human cognition
    2025/09/04
    Hi friends! We're taking a much-needed summer pause—we'll have new episodes for you later in September. In the meanwhile, enjoy this pick from our archives! ------- [originally aired June 1, 2023] There's a common story about the human past that goes something like this. For a few hundred thousand years during the Stone Age we were kind of limping along as a species, in a bit of a cognitive rut, let’s say. But then, quite suddenly, around 30 or 40 thousand years ago in Europe, we really started to come into our own. All of a sudden we became masters of art and ornament, of symbolism and abstract thinking. This story of a kind of "cognitive revolution" in the Upper Paleolithic has been a mainstay of popular discourse for decades. I’m guessing you’re familiar with it. It's been discussed in influential books by Jared Diamond and Yuval Harari; you can read about it on Wikipedia. What you may not know is that this story, compelling as it may be, is almost certainly wrong. My first guest today is Dr. Eleanor Scerri, an archaeologist at the Max Planck Institute for the Science of Human History, where she heads the Pan-African Evolution research group. My second guest is Dr. Manuel Will, an archaeologist and Lecturer at the University of Tübingen in Germany. Together, Eleanor and Manuel are authors of a new paper titled 'The revolution that still isn't: The origins of behavioral complexity in Homo sapiens.' In the paper, they pull together a wealth of evidence showing that there really was no cognitive revolution—no one watershed moment in time and space. Rather, the origins of modern human cognition and culture are to be found not in one part of Europe but across Africa. And they’re also to be found much earlier than that classic picture suggests. Here, we talk about the “cognitive revolution" model and why it has endured. We discuss a seminal paper from the year 2000 that first influentially challenged the revolution model. We talk about the latest evidence of complex cognition from the Middle Stone Age in Africa—including the perforation of marine shells to make necklaces; and the use of ochre for engraving, painting, and even sunblock. We discuss how, though the same complex cognitive abilities were likely in place for the last few hundred thousand years, those abilities were often expressed patchily in different parts of the world at different times. And we consider the factors that led to this patchy expression, especially changes in population size. I confess I was always a bit taken with this whole "cognitive revolution" idea. It had a certain mystery and allure. This new picture that’s taking its place is certainly a bit messier, but no less fascinating. And, more importantly, it’s truer to the complexities of the human saga. Alright friends, on to my conversation with Eleanor Scerri & Manuel Will. Enjoy! A transcript of this episode is available here. Notes and links 3:30 – The paper by Dr. Scerri and Dr. Will we discuss in this episode is here. Their paper updates and pays tribute to a classic paper by McBrearty and Brooks, published in 2000. 6:00 – The classic “cognitive revolution” model sometimes discussed under the banner of “behavioral modernity” or the “Great Leap Forward.” It has been recently featured, for instance, in Harari’s Sapiens. 11:00 – Dr. Scerri has written extensively on debates about where humans evolved within Africa—see, e.g., this paper. 18:00 – A study of perforated marine shells in North Africa during the Middle Stone Age. A paper by Dr. Will and colleagues about the use of various marine resources during this period. 23:00 – A paper describing the uses of ochre across Africa during the Middle Stone Age. Another paper describing evidence for ochre processing 100,000 years ago at Blombos Cave in South Africa. At the same site, engraved pieces of ochre have been found. 27:00 – A study examining the evidence that ochre was used as an adhesive. 30:00 – For a recent review of the concept of “cumulative culture,” see here. We discussed the concept of “cumulative culture” in our earlier episode with Dr. Cristine Legare. 37:00 – For an overview of the career of the human brain and the timing of various changes, see our earlier episode with Dr. Jeremy DeSilva. 38:00 – An influential study on the role of demography in the emergence of complex human behavior. 41:00 – On the idea that distinctive human intelligence is due in large part to culture and our abilities to acquire cultural knowledge, see Henrich’s The Secret of Our Success. See also our earlier episode with Dr. Michael Muthukrishna. 45:00 – For discussion of the Neanderthals and why they may have died out, see our earlier episode with Dr. Rebecca Wragg Sykes. Recommendations Dr. Scerri recommends research on the oldest Homo sapiens fossils, found in Morocco and described here, and new ...

    From the archive: Of molecules and memories
    2025/08/21
    Hi friends! We're taking a much-needed August pause—we'll have new episodes for you in September. In the meanwhile, enjoy this pick from our archives! _____ [originally aired February 8, 2024] Where do memories live in the brain? If you've ever taken a neuroscience class, you probably learned that they're stored in our synapses, in the connections between our neurons. The basic idea is that, whenever we have an experience, the neurons involved fire together in time, and the synaptic connections between them get stronger. In this way, our memories for those experiences become minutely etched into our brains. This is what might be called the synaptic view of memory—it's the story you'll find in textbooks, and it's often treated as settled fact. But some reject this account entirely. The real storehouses of memory, they argue, lie elsewhere. My guest today is Dr. Sam Gershman. Sam is Professor of Psychology at Harvard University, and the director of the Computational Cognitive Neuroscience Lab there. In a recent paper, he marshals a wide-ranging critique of the synaptic view. He makes a compelling case that synapses can't be the whole story—that we also have to look inside the neurons themselves. Here, Sam and I first discuss the synaptic view and the evidence that seems to support it. We then talk about some of the problems with this classic picture. We consider, for example, cases where memories survive the radical destruction of synapses; and, more provocatively, cases where memories are formed in single-celled organisms that lack synapses altogether. We talk about the dissenting view, long lurking in the margins, that intracellular molecules like RNA could be the real storage sites of memory. Finally, we talk about Sam's new account—a synthesis that posits a role for both synapses and molecules. Along the way we touch on planaria and paramecia; spike-timing dependent plasticity; the patient H.M.; metamorphosis, hibernation, and memory transfer; the pioneering work of Beatrice Gelber; unfairly maligned ideas; and much, much more. Before we get to it, one important announcement: Applications are now open for the 2024 Diverse Intelligences Summer Institute (or DISI)! The event will be held in beautiful, seaside St Andrews, Scotland, from June 30 to July 20. If you like this show—if you like the conversations we have and the questions we ask—it's a safe bet that you'd like DISI. You can find more info at disi.org—that's disi.org. Review of applications will begin on Mar 1, so don't delay. Alright friends, on to my conversation about the biological basis of memory with Dr. Sam Gershman. Enjoy! Notes and links 4:00 - A general audience article on planarian memory transfer experiments and the scientist who conducted them, James V. McConnell. 8:00 - For more on Dr. Gershman’s research and general approach, see his recent book and the publications on his lab website. 9:30 - A brief video explaining long-term potentiation. An overview of “Hebbian Learning.” The phrase “neurons that fire together wire together” was, contrary to widespread misattribution, coined by Dr. Carla Shatz here. 12:30 - The webpage of Dr. Jeremy Gunawardena, Associate Professor of Systems Biology at Harvard University. A recent paper from Dr. Gunawardena’s lab on the avoidance behaviors exhibited by the single-celled organism Stentor (which vindicates some disputed, century-old findings). 14:00 - A recent paper by C. R. Gallistel describing some of his views on the biological basis of memory. 19:00 - The term “engram” refers to the physical trace of a memory. See recent reviews about the so-called search for the engram here, here, and here. 20:00 - An article on the importance of H.M. in neuroscience. 28:00 - A review about the phenomenon of spike-timing dependent plasticity. 33:00 - An article, co-authored by former guest Dr. Michael Levin, on the evidence for memory persistence despite radical remodeling of brain structures. See our episode with Dr. Levin here. 35:00 - A study reporting the persistence of memories in decapitated planarians. A popular article about these findings. 36:30 - An article reviewing one chapter in the memory transfer history. Another article reviewing evidence for “vertical” memory transfer (between generations). 39:00 - For more recent demonstrations of memory transfer, see here and here. 40:00 - A paper by Dr. Gershman, Dr. Gunawardena, and colleagues reconsidering the evidence for learning in single cells and describing the contributions of Dr. Beatrice Gelber. A general audience article about Gelber following the publication of the paper by Dr. Gershman and colleagues. 45:00 – A recent article arguing for the need to understand computation in single-celled organisms to understand how computation evolved more generally. 46:30 – Another study of classical conditioning in paramecia, led by Dr. ...

    From the archive: Consider the spider
    2025/08/07
    Hi friends! We're taking a much-needed August pause—we'll have new episodes for you in September. In the meanwhile, enjoy this pick from our archives! _____ [originally aired May 30, 2024] Maybe your idea of spiders is a bit like mine was. You probably know that they have eight legs, that some are hairy. Perhaps you imagine them spending most of their time sitting in their webs—those classic-looking ones, of course—waiting for snacks to arrive. Maybe you consider them vaguely menacing, or even dangerous. Now this is not all completely inaccurate—spiders do have eight legs, after all—but it's a woefully incomplete and drab caricature. Your idea of spiders, in other words, may be due for a refresh. My guest today is Dr. Ximena Nelson, Professor in the School of Biological Sciences at the University of Canterbury, in New Zealand. Ximena is the author of the new book, The Lives of Spiders. It’s an accessible and stunningly illustrated survey of spider behavior, ecology, and cognition. In this conversation, Ximena and I do a bit of ‘Spiders 101’. We talk about spider senses—especially how spiders use hairs to detect the minutest of vibrations and how they see, usually, with four pairs of eyes. We talk about web-making—which, by the way, the majority of spiders don't do—and silk-making—which all do, but for more reasons than you may realize. We talk about how spiders hunt, jump, dance, pounce, plan, decorate, cache, balloon, and possibly count. We talk about why so many spiders mimic ants. We take up the puzzle of “stabilimenta”. We talk about whether webs constitute an extended sensory apparatus—like a gigantic ear—and why spiders are an under-appreciated group of animals for thinking about the evolution of mind, brain, and behavior. Alright friends, this one is an absolute feast. So let's get to it. On to my conversation with Dr. Ximena Nelson. Enjoy! A transcript of this episode is available here. Notes and links 3:00 – A general audience article about our “collective arachnid aversion” to spiders. 8:00 – An academic article by Dr. Nelson about jumping spider behavior. 8:30 – In addition to spiders, Dr. Nelson also studies kea parrots (e.g., here). 12:00 – A popular article about the thousands of spider species known to science—and the thousands that remain unknown. 16:30 – A popular article about a mostly vegetarian spider, Bagheera kiplingi. 18:00 – For the mating dance of the peacock spider, see this video. 20:00 – A recent study on spider “hearing” via their webs. 24:00 – The iNaturalist profile of the tiger bromeliad spider. 29:30 – A recent study of extended sensing in humans during tool use. 33:00 – A popular discussion of vision (and other senses) in jumping spiders. 40:00 – An earlier popular discussion of spider webs and silk. 45:00 – For a primer on bird’s nests, see here. 48:00 – An article describing the original work on how various drugs alter spiders’ webs. 49:00 – A recent salvo in the long-standing stabilimenta debate. 54:00 – A video about “ballooning” in spiders. 57:00 ­– An article by Dr. Nelson and a colleague about jumping spiders as an important group for studies in comparative cognition. 1:01:00 – A study of reversal learning in jumping spiders, which found large individual differences. 1:07:00 – A study of larder monitoring in orb weaver spiders. 1:10:00 – A study by Dr. Nelson and a colleague on numerical competence in Portia spiders. 1:16:00 – An academic essay on the so-called insect apocalypse.

  • The shaman with a thousand faces

    The shaman with a thousand faces
    2025/07/24
    When you hear the word "shaman," I'm guessing a web of associations starts to form in your mind. Perhaps you imagine strange ceremonies and strong substances; maybe you think of an earlier time when magic and superstition reigned. But shamanism is not just some relic of the past, or a curio from exotic lands. It's part of our present, and it will almost certainly be part of our future. This is because the roots of shamanism lie within us all. My guest today is Dr. Manvir Singh. Manvir is an Assistant Professor of Anthropology at the University of California, Davis and a regular contributor to The New Yorker. He's also the author of a new book—Shamanism: The Timeless Religion. Here, Manvir and I talk about his fieldwork with Mentawai shamans in Indonesia. We discuss what makes a shaman a shaman and consider the cognitive building blocks that make shamanism so widespread and so appealing. We discuss the shamanic origins of Abrahamic religions. We consider how, over the course of history, shamanism has repeatedly resurged, despite attempts to snuff it out. And we also talk about the various forms and flavors that shamanism takes in contemporary Western societies. Along the way, Manvir and I touch on: drumming, fasting, and the “dark tent”; Jesus; experimental Edens; witches, prophets, and messiahs; glossolalia; disenchantment and re-enchantment; the rise of neoshamanism; Paleolithic rock art; hedge wizards and tech CEOs; Western exceptionalism; and the routinization of charisma. If you enjoy this episode, I highly recommend that you check out Manvir's book—it's a captivating blend of narrative and ideas and it goes far beyond what we were able to talk about here. I'll also flag that this is Manvir's second time on Many Minds. Back in July of 2020 we had another conversation—broader in scope—where we talked about shamanism but also Manvir's work on witches, stories, and music. So you might check that one out as well. Alright friends, on to my conversation with Dr. Manvir Singh. Enjoy! A transcript of this episode is available here.

    Varieties of childhood
    2025/07/10
    Childhood is a special time, a strange time. Children are adored and catered to—they're given their own menus and bedrooms. They're considered delicate and precious, and so we cushion them from every imaginable risk. Kids are encouraged to play, of course—but very often it's under the watchful eye of anxious adults. This, anyway, is how childhood looks in much of the United States today. But is this the way childhood looks everywhere? Is this the way human childhoods have always been? My guests today are Dr. Dorsa Amir and Dr. Sheina Lew-Levy. Dorsa is an Assistant Professor of Psychology & Neuroscience at Duke University, where she runs the Mind and Culture Lab. Sheina is an Associate Professor of Psychology at Durham University in the UK, where she co-directs the Forager Child Studies research group. Both Sheina and Dorsa have spent much of their careers thinking about how childhoods differ across cultures—and why. In this conversation, I talk with Dorsa and Sheina about their fieldwork with indigenous groups in Ecuador and the Congo, respectively. We discuss the different ways that childhood differs in these places—for instance, in terms of parents' attitudes toward risk, in terms of the social structures and activities in which kids are embedded, and in terms of the freedom that children are granted. We discuss developmental psychology's "WEIRD problem." We talk about the quasi-autonomous cultures that children create among themselves—sometimes called "peer cultures"—and discuss how these kid-driven cultures end up shaping and benefit the larger community. Along the way, we touch on adult supremacy, adverse childhood experiences, walking the forest and climbing papaya trees, parenting norms, ding dong ditch and "nananabooboo", the pioneering work of the folklorists Iona and Peter Opie, teaching, toys, and the enduring question of what childhood is for. Alright friends, lots to think about here. On to my conversation with Sheina Lew-Levy and Dorsa Amir. Enjoy! A transcript of this episode is available here.
